23、rdization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right t

24、o be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Sta

25、ndards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an In

26、ternational Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

28、vedIntroduction For the purpose of evaluating the quality of a dataset, clearly defined procedures must be used in a consistent manner. This enables data producers to express how well their product meets the criteria set forth in its product specification and enables data users to establish the exte

29、nt to which a dataset meets their requirements. The quality of a dataset is described using two components: a quantitative component and a non-quantitative component. The objective of this International Standard is to provide guidelines for evaluation procedures of quantitative quality information f

30、or geographic data in accordance with the quality principles described in ISO 19113. It also offers guidance on reporting quality information. This International Standard recognizes that a data producer and a data user may view data quality from different perspectives. Conformance quality levels can

31、 be set using the data producers product specification or a data users data quality requirements. If the data user requires more data quality information than that provided by the data producer, the data user may follow the data producers data quality evaluation process flow to get the additional in

32、formation. In this case, the data user requirements are treated as a product specification for the purpose of using the data producer process flow. The quality evaluation procedures described in this International Standard, when applied in accordance with ISO 19113, provide a consistent and standard

33、 manner to determine and report the quality information in a dataset.

34、 reserved 1Geographic information Quality evaluation procedures 1 Scope This International Standard provides a framework of procedures for determining and evaluating quality that is applicable to digital geographic datasets, consistent with the data quality principles defined in ISO 19113. It also e

35、stablishes a framework for evaluating and reporting data quality results, either as part of data quality metadata only, or also as a quality evaluation report. This International Standard is applicable to data producers when providing quality information on how well a dataset conforms to the product

36、 specification, and to data users attempting to determine whether or not the dataset contains data of sufficient quality to be fit for use in their particular applications. Although this International Standard is applicable to all types of digital geographic data, its principles can be extended to m

37、any other forms of geographic data such as maps, charts and textual documents. 2 Conformance This International Standard defines three classes of conformance: one for quality evaluation procedures, one for evaluating data quality, and one for reporting quality information. The abstract test suites f

38、or the three classes of conformance are given in Annex A. 3 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (inc

39、luding any amendments) applies. ISO 19113:2002, Geographic information Quality principles ISO 19115:2003, Geographic information Metadata 4 Terms and definitions For the purposes of this document, the terms and definitions given in ISO 19113 and ISO 19115 (some of which are repeated for convenience)

Th

48、e phases of the life cycle considered here are specification, production, delivery, use and update. Annex B describes some specific dataset-related operations to which quality evaluation procedures are applicable. The process for evaluating data quality is a sequence of steps to produce and report a

49、 data quality result. A quality evaluation process consists of the application of quality evaluation procedures to specific dataset-related operations performed by the dataset producer and the dataset user. Processes for evaluating data quality are applicable to static datasets and to dynamic datasets. Dynamic datasets are datasets that receive updates so frequ
